Back in March 2016, Espressif Announced the ESP8285 Wi-Fi Chip, a supposed killer of the favorite ESP8266 chip. The new chip is an ESP8266, but with the flash memory onboard – 1MB flash memory. Espressif’s ESP8285 delivers highly integrated Wi-Fi SoC solution to meet users’ constant demands for efficient power usage, compact design and reliable performance in the […]
PacketMonitor32 – An ESP32-Based Packet Monitor with OLED
https://www.electronics-lab.com/packetmonitor32-esp32-based-packet-monitor-oled/
Wi-Fi Packet Monitors are usually a computer program or sometimes a piece of computer hardware that can be used to intercept and log traffic over a Wi-Fi network. My favorite software tool of all is the popular Wireshark which I have used several times for hacking Wi-Fi based hardware, like integrating the common Wi-Fi smart socket […]
ESP8266: Monitoring Power Consumption
https://www.electronics-lab.com/esp8266-monitoring-power-consumption/
Dani Eichhorn @ thingpulse.com writes: In this post I’m going to show you how you can monitor the power consumption of your battery driven (ESP8266/ ESP32) device. Measuring the power consumption over a full activity/ sleep cycle is the precondition to optimize your code for a longer battery runtime. Only with a reliable tool you […]

This instrucatables show how to make an ESP8266 version WiFi Analyzer clone. WiFi Analyzer is a handy app in Android, it help to visualize the WiFi signal information around you. It is very useful for helping select a right channel for setting a new AP. If you selected a channel that as same as another […]
ESP8266 based e-paper WiFi weather station
https://www.electronics-lab.com/esp8266-based-e-paper-wifi-weather-station/
Erich Styger documented his experience building Daniel Eichhorn’s e-paper weather station with a custom enclosure: Using e-paper for a weather station is an ideal solution, as the data does not need to be updated often. By default, the station reaches out every 20 minutes for new data over WiFi and then updates the display. Daniel […]
Decoding and Encoding JSON with Arduino or ESP8266
https://www.electronics-lab.com/decoding-encoding-json-arduino-esp8266/
In this blog post you’re going to learn how to decode (parse a JSON string) and encode (generate a JSON string) with the ArduinoJson library using the Arduino with the Ethernet shield. This guide also works with the ESP8266 and ESP32 Wi-Fi modules with small changes. Decoding and Encoding JSON with Arduino or ESP8266 – […]

Raspberry Pi Publishing MQTT Messages to ESP8266
https://www.electronics-lab.com/raspberry-pi-publishing-mqtt-messages-esp8266/
Rui @ randomnerdtutorials.com tipped us with his latest tutorial. He writes: In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs from an ESP8266 using MQTT protocol. You can replace those LEDs with any output (like a relay that controls a lamp). Raspberry Pi Publishing MQTT Messages to […]
